GRB 150626: TAROT Calern observatory optical observations
----------------------------------------------------------------------
Klotz A., Turpin D. (IRAP-CNRS-OMP),
Boer M., Gendre B., Siellez K., Dereli H., Bardho O. (UNS-CNRS-OCA),
Atteia J.L. (IRAP-CNRS-OMP) report:

We imaged the field of GRB 150626 detected by INTEGRAL
(trigger 7145) with the TAROT robotic telescope (D=25cm)
located at the Calern observatory, France.

The observations started -40.2s after the GRB trigger
(-44.5s after the notice). The elevation of the field increased from
35 degrees above horizon and weather conditions
were XXX.

---- NO
The date of trigger : t0 = 2015-06-26T20:53:51.936

The first image is trailed with a duration of 60.0s
(see the description in Klotz et al., 2006, A&A 451, L39).
We do not detect any OT with a limiting magnitude of:
t0+-40.2s to t0+19.8s : R > 15.1

The second image is 30.0s exposure in tracking mode:
t0+67.2s to t0+97.2s : R > 16.2

We co-added a series of exposures:
t0+67.2s to t0+314.9s : R > 17.7
---- YES
We detect a new fading source in the error box given by INTEGRAL
We detected the candidate couterpart mentioned by XXX et al. (GCNC XXXX)
at the following position (+/- 3 arcsec):

RA(J2000.0) = XXh XXm XX.XXs
DEC(J2000.0) +XXd XX' XX.X"

OT was R~XX.X at -40.2s after GRB.
----

Magnitudes were estimated with the nearby USNO-B1 stars
and are not corrected for galactic dust extinction.

N.B. Galactic coordinates are lon= 73.1219 lat= -2.0620
and the galactic extinction in R band is 1.4 magnitudes
estimated from D. Schlegel et al. 1998ApJ...500..525S.
